TUCSON, Ariz. — Investigators are keeping the family of a 6-year-old girl who disappeared away from their home in Tucson, Ariz.
Authorities say they decided to keep the family of first-grader Isabel Mercedes Celis (SELL-uhs) away from the home after a search early Monday of the house by FBI dogs.
Police Chief Robert Villasenor says the information turned up by the dogs required follow-up but he wouldn't reveal what was found.
Two days of searching by scores of police and officers from several agencies have failed to locate Isabel.
Police says she was last seen by her family in her bedroom at 11 p.m. Friday. She was discovered missing at 8 a.m. Saturday.
